GAP-SPINBLE.

Application led December 12, 1908.

Specification of Serial No. 467,277.

To all wlw/fri it may concern:

Be it known that we, BENJAMiN PicKLEs, of Pawtucket, county of Providence, and State of Rhode Island, and FRANK vWoon- Hnnn, of Providence, county of Providence, and -State of Rhode Island, have invented a new and useful lm rovement in Cap-Spindles, of which the following is a specification.

This invention has reference to `an improvement in cap spindles for cap spinning machines and more particularly to an improvement in a combined anti-friction bearing and oil reservoir for the spindle of cap spinning machines.

The object of our invention is to improve the construction of cap spinning machines whereby the friction on the whirls is reduced and the spindles more perfectly lubricated for a longer period than has heretofore been done.

Our invention consists in the peculiar and novel construction of a combined anti-friction bearing and oil reservoir for the dead spindles of cap spinning machines, said combined ball bearing and oil reservoir having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a vertical sectional view of a reciprocating rail, whirl and sleeve and dead spindle (shown in full) of a cap spinning machine provided with our im roved combined anti-friction bearing and oi reservoir, shown in section. Fig. 2 is an enlarged top plan view of the anti-friction bearing and oil reservoir, showing the same before the balls are secured in the combined raceway and oil reservoir. Fig. 3 is a vertical sectional view taken on line 3 3 of Fig. 2, showing the construction of the combined anti-friction bearing and oil reservoir before the balls are secured in the same, and Fig. i is a vertical sectional view similar to Fig. 3, showing the balls secured in the raceway and oil reservoir.

In the drawings, a indicates the reciprocating rail, l) the dead spindle, c the whirl, d the whirl sleeve of a cap spinning machine, and e our improved combined anti-friction bearing and oil reservoir which consists of a body member 5 constructed to have a flat circular base 6 in the bottom of which is a shallow circular cavity 7 and in the top a circular groove forming an oil trough 8 connected with the cavity 7 by the oil holes 9 9, a concentric circular hub 10 having a central hole l1 for the spindle b and a concentric circular and comparatively deep recess 12 in the top, having a circular groove 13 in the bottom and the inner and outer side walls 14 and 15 brought to a thin edge and forming a combined. raceway and oil reservoir, as shown in Fig. 3, a series of balls 16 15 movably secured in the recess 12 by forcing the thin edges of the side walls 14 and 15 over the balls, as shown in Fig. L1, by the use of dies or other means, and a felt washer 17 shaped to fit in the recess 7 and having a central hole 18 which snugly fits the spindle .72, as shown in Fig. l.

The hat bottom of the on the balls 16 16 (as shown in Fig. 1) which roll in a circular direction in the groove 13 and form an anti-friction bearing for the whirl and sleeve. The recess 12 or oil reservoir is filled with oil to a predetermined height, which lubricates the bearing. When in operation the movement or centrifugal force of the balls in the recess 12 and oil reservoir combined with capillary attraction cause the oil to flow up and out of the oil reservoir or recess 12 and down to the oil trough 8 from which it flows downward through the oil holes 9 9 to the felt washer 17, saturating the same with oil. The vertical reciprocating movement of the reciprocating rail a causes the oil saturated washer 17 to wipe up and down on the spindle l) and lubricate the spindle. The felt washer 17 may also be lubricated by dropping oil into the oil trough 8.

By this construction we produce a combined anti-friction bearing and oil reservoir for cap spindles, adapted to reduce friction on the whirl and to more perfectly oil the spindle for a longer period than has heretofore been done.

Having thus described our invention, we claim as new and desire to secure by Letters Patent A combined ball bearing and oil reservoir for the dead spindles of cap spinning machines, consisting of a body member having a flat circular base in the bottom of which is a shallow circular cavity and in the top a circular groove forming an oil trough connected with the cavity in the bottom by oil holes, a concentric circular hub having a central hole for the spindle, and a concentric circular and comparatively deep recess in the top having a circular groove in the bottom, and inner and outer side walls brought to a thin edge and forming a combined race- Way and oil reservoir, a series of balls in the whirl c rests directly circular recess, e felt washer n the shallow l naines to this speciicetion in the presence of recess in the bottoni of tlie body member i two subsciil/ing Witnesses. adapted to convey oil te the spindle, means BENJAM N PCKLES. for movably securing the balls in the circular FRANK VVGOHEA). 5 recess7 and means for conducting oil from the Witnesses:
